Application tiled October 24, 1908. leiht No. 459.417.

To all 'whom 'ii' muy concern:

Be it known that. I MAn'iis4 J. (,iiius'rnxsus, a citizen of the nited States, residing at Chica o, county of Cook, aiul State of llliiiois, inve invented certain new and uscfal Im )rovi-ments in Mechanisms for lilcvating '1|ifids, of which the following is a specification.

My invention relates to mechanisms for raising or elevating liquids, and more particuhirlv to that class of the sinne especially ap ilica )le 'for raising liquids from deep wels, as -for example,'oil-wells and like places.

'l`lie object of ni invention is to provide a mechanism of the character mentioned, which will be of such construction as to be adapted to raise or elevate liquids by means of eonipiessed air.

A further object of inv invention is to provide a mechanism of t ie character inentioned, which will be of the highest possible ctliciency, and further, one which will be extremely simple of construction, hence. of low cost to manufacture. ()tlier objects will appear hereinafter.

With these objects in view, my invention consists in a liquid -elevuting iueclian'isni characterized as above mentioned, and in certain details of construction and arrangement of partsall as will be liereitiafter more fullv described aiid particularly pointed oiit in tho claim.

My invention will be more readily understood by reference to the accompanying drawings fortuin n part of this specification. aiul in wliic i,

Figure l is a longitudinal section of my mechanism showing the application of the same. and Fig. 2 is a-transvenie section there# of taken on the line w-m o Fig. 1.

Referring now to the dra ings, 1 indicates' u tuluilar metal casing, the sinne beiiig`of any suitable diameter, but ncferably of about eight inches.' Central y positioned, and longitudinally extending witliiu the tipper portion t?, said easing l is an air'delivery pipe L). t the. pi ie 1 and forming a cmupression chatilla-r. o the t-.xteriorly projecting upper extremity of the pi n. .5, is suitably secured, but preferably threaded, n hood member or easing :t ol' any ordinary or preferred design into which leads a compressed air-supply a diameter less tlni u that ofl pipe 4, the latter being' connected with it|i suitable air-coni n'essing means (not shown). Suitably secui'eti. preferably. h v means of au intermediate annular connecting member 5. to the lower end portion of said pipe L. is :i pipe t1, of a diameter less than that of the pipe 2, preferably of u diameter one-half that of said pipe 2. T is a disk-valve, tlie saine heilig adapted to iiorn'ially close the lower extremity of the pipe tl. lt is understood, however. that l do not wish to be liniited to the specitic forni of valve used. as any other valve of suitable construction might be employed without departing from'tlie spirit of in v invention. Said valve 'i' is secured to the lower extremity of the vulve-stein S, the upper end portion S) of said valve-stein projecting through the hood 'member 3, it being preferably threaded therein as shown. 10 is an actuating hand-wheel lixcd to the upper extremity of said valve-stein 8. A spider 1l provided in the louer portion of said pipe 2 Serves asu means of centrally guiding said valve-stein. )oncentrically arraugul upon and suitably Securtal, preferably by means of an internally and externally threaded amiti- -lar member l2, to the lower cud portion of the )ipe this an air nozzle 13. Said nozzle is pre erably cylindrical in form, the 'upper cxtremity being open and the lower tapering extremity 14 thereof climat. 'lhe annular connecting member l2 is provided with a pluralit of circular slots or ierforations l5. prefere ly three in nuinber or obvious reasons.

The operation of my mechanism is extremely simple, it being as follows: Highly` compressed nir is admitted through the snpply-pipe 4, said air passing through the des' very-pipes 2 and 6 to the lower extremity of the hitter, which is submerged say tw hundred or three hundred feet below t o surface of the li uid to be raised. The valve-stem 8 ist n actiiated,- more specilicall rotated, S0 as to lower.'that is. open the dish-valve 7. the latter in which case. assuming the .'ition shown in dotted lines in Figfl. so doing, compressed air is dischar ed into the nozzle 13, which oliviously tirects tlie saine upwardly through the perforations 15 in the member l2 and out of 4the upwardly opening mouth 16- tliereof. U n leaving the mouth of the nozzle 13, tie compressed air contacts the Il VlllLBlJ-l COPY osmose column of liquid contained within the ciising l, which it pierces or breaks forcing the liquid above it upward through said casing 1 to the mouth 17 thereof, or to the sirface of the earth.

By the employment of a nozzle and a perforated annular connecting member there for of a construction as described, it is 0bvious that the compressed air discharged from the lower extremity of the pipe 6 will be immediately directed upwardly, and will he broken up and evenly and uni ornily distributed within tlie casing i. hence, under the column of liquid raised, resulting in obvious advantages. By the provision of the pipe 2 in the upper portion of the casini;r 1, said pi )e being of a greater diameter t nn that o the puo 6, the column of liquid upon leaving the lower portion of the casing 1 in which is contained the pi )e 6 will be caused to lengthen, tliereb ena ling the compressed air to be more e ective than it could otherwise be, if a delivery pi of uniform diameter were employed, it eing uiiderstood, of course, that in forcing the li( uid upward by means of compressed air, ,it is alwa s desirablev to have a thick stratum of liquid above the air in order to prevent the air from passing through it.

While I have shown what I deem to be the preferable form of my device, l do not wish to be limited thereto as there might be many changes made in the details of construction and arrangement of parts without de nirting from the spirit of my invention. Iaving described my invention what I claim as new and desire to secure by Letters Patent, is:

In a device of the class described, the combination with a tubular casing of comparatively large diameter, of a compression chamber of less diameter than said tubular casing and centrally positioned within the upper end thereof, a bell shaped hood closing the upper end of said chamber, an annular reducing member secured to the lower end of said chamber, lin air delivery pipe of less diameter than said chamber extending downwardly from said reducing member, a disk valve adapted to close the lower opening of said air delivery ipe. a stem on said valve extending upward y throligh said air delivery pipe and said compression chamber and threaded through said hood, said -hood being provided with a sleeve to receive said stem, an upwardly openin cylindrical nozzle encircling the lower en )ortion of said air delivery pipe, an annu ar rforated member interposed between the ower end of said pi and th(` .adjacent wall of Said nozzle for olding the latter in position, and an nir supply pipe leading into said compression chamber through said hood, substantially as described.

In testimony whereof I have .signed my iimne to this specification in thepresence of two subscribing witnesses.
